[avr-gcc-list] Can someone benchmark this option please

[Andy H]

Hi,

I have noted problem where gcc is optimizing if-then-else constructs - 
with disastrous results. For example:

if (a  >= 0)
 return 8;
else
return 0;

(This is now reported as bug.)

Can folks try the following gcc option

-fno-if-conversion

on their own code at -Os optimization, and see if this produce 
better/worse or same code? This will help figure if the whole pass 
should be skipped - or whether it still contains useful optimizations.
